Created by Cake

Although technology has made it possible to get in touch with companies through emails and even social media, writing formal business letters is a skill you must master as an aspiring professional. 

Writing business letters is necessary because it is still a common way to deal with professional documentation. 

There are quite a few types of formal business letters you will find in your career, such as:

  • Cover letters
  • Welcome letters
  • Interview follow-up letters
  • Recommendation letters
  • Thank you letters
  • Letters of resignation
  • Termination letters, and so on

With so many types, it is okay to be confused about how to write a business letter; Nonetheless, you also need to use the proper formal letter format. It is not enough to be grammatical.

Parts of a Business Letter

There are different ways to arrange the layout of a formal letter; We recommend including at least the following parts of business letters.

🖋 Your Contact Information 

A vital part of the business letter format is to include all of your contact information; therefore, you should include the following details in your business letter heading:

  • Your full name (and your job title/company if you have one)
  • Your address (including city and Zipcode)
  • Your phone number
  • Your email address (optional)

🖋 The Date

Avoid using abbreviations when you write the date in a formal business letter. The date format should be: 

  • Month/Day/Year (for example, April 6, 2022)

🖋 The Recipient’s Contact Information 

The following section needs to include the information of the letter recipient, such as:

  • Their full name
  • Their job title/company
  • Their company’s address (including city and Zip code)
  • Their phone number

🖋 The Salutation

In this section, people who want to write formal letters need to think of a proper opening. You can try the following ways to start your formal business letter:

  • If you don’t know who to address the letter to: To whom it may concern
  • When you know who the recipient is: Dear Ms./Mrs./Mr. [the recipient’s last name]
  • If you and the recipient have a close relationship: Dear [the recipient’s first name]

🖋 The Body 

Another vital part of formatting letters is a great body. Just like when you write an article, a professional letter needs to have a proper introduction where you add a friendly salutation and then state the main point.

In another paragraph, you should cover the main point and add supporting details. Finally, add a closing paragraph to reiterate your purpose or restate your request. 

🖋 The Closing Salutation 

The next part of the business letter is writing a suitable closing salutation. You need to check whether it is fully formal or not. Here are some examples of business letter closing salutations:

For formal letters:

  • Respectfully yours,
  • In appreciation,
  • Sincerely yours,
  • Cordially,
  • Sincerely,

For more casual letters:

  • Best regards,
  • Thank you for your time,
  • Kind regards,
  • Best,
  • Stay well, 

Make sure to consider the types of formal letters you are writing and choose a closing salutation that fits your formal business letter.

🖋 Your Signature

Every formal business letter needs to finish with your signature right below your closing salutation. Remember to leave enough space for your physical signature (or add a digital one). Finish by typing your full name and title. 

How to Format a Business Letter

Now that you know the parts of business letters, it’s time to talk about how to format a business letter. You have to consider many things, such as which layout to use or which font suits your formal business letter best. 

🎯 Choose a format that suits you. 

There are several ways to write a formal business letter. There are several styles and formats you can use, such as the block letter format, the modified block letter format, and the semi-block letter format. Here we tell you more about their differences for you to get familiar with different layouts of business letters.

  • Block Format

It is also known as the full block style. It is the most common style out there. How to write a block format business letter? You need to align all your text to the left when writing a block format business letter. Each line is single-spaced, and none of them is indented. 

Moreover, skip a line if you are writing a different paragraph (it will look like a double-spaced line). Do not forget to add all the parts of the business letter we mentioned above. Do not worry if you are still confused. We will provide you with a full block letter format example later in the article.

  • Modified Block Format

It is also known as the Indented form. The modified block letter format is another writing style. Similar to the full block letter format, your text should be left-justified and single-spaced. However, your contact information, the date, closing salutation, and signature are all either moved to the center or aligned to the right. 

There is, too, an example of a letter in modified block format later in the article.

  • Semi-Block Format

Not as commonly used as the others due to its being a bit less formal, the semi-block letter format is very similar to both the block letter format and the modified one. 

While the text is aligned to the left, you need to indent every paragraph. Additionally, for the layout of business letters in semi-block format, your contact information, the date, closing salutation, and signature should all be right-justified or aligned to the center. 

We also offer an example letter in semi-block format later in this article.

🎯 Pay attention to font style and size.

Besides using a professional letter format, you should consider which font style is appropriate. The font size can also help or hinder the letter’s readability. The acceptable standard size for formal letter headers is 12 points. 

When it comes to fonts in business letter writing, the commonly accepted ones are Arial and Times New Roman. However, you can also consider Helvetica, Open Sans, Calibri, Book Antiqua, and Georgia. 

🎯 Adjust spacing and margins.

Keep spacing in mind when you are doing the letterhead formatting. You need to leave enough space between the different parts of your letter (Your contact information, the receiver’s contact information, the content, and so on).

Additionally, it is recommended to use a single space for your text in a formal letter. Finally, a formal business letter format has a one-inch margin, the default margin size in most software.
